About this Gig
Gig Description
Got a messy spreadsheet or dataset that's hard to make sense of?
I clean and organize raw data removing duplicates, fixing inconsistent formatting, handling missing values and turn it into clear charts and visual summaries that actually make sense at a glance.
I recently completed a full retail sales analytics project: cleaning raw sales data from scratch and building visualizations that surfaced what mattered most to the business. I work with Python (Pandas, NumPy) for the cleaning and analysis, and Matplotlib/Seaborn or Excel for the final visuals, depending on what fits your needs.
What I can help with:
- Cleaning messy, inconsistent, duplicate, or incomplete data (CSV, Excel, JSON)
- Standardizing formats, fixing column types, handling missing values
- Clear charts and graphs (bar, line, pie, scatter, etc.)
- Excel dashboards or Python-based visual reports
- A short plain-language summary of key patterns in your data
I'm early in my freelance career, which means competitive pricing, full attention on your project, and direct communication no agency hand-offs, no vague timelines. Send me a sample of your data before ordering and I'll tell you honestly what's realistic.

FAQ
What file formats can you work with?
CSV, Excel (.xlsx), and JSON are the most common. Send a sample first if you're unsure. I'll confirm before you order.
My data is really messy — duplicate rows, missing values, inconsistent formatting. Can you handle that?
Yes, that's exactly what this gig is for. Send a sample and I'll tell you honestly how much cleaning it needs before you order.
Do you just clean the data, or do you also make charts
Both. Cleaning is the foundation, but every package includes visualizations so you can actually see what the data shows.
Can I get the cleaned data file as well as the charts?
Yes, you'll receive both the cleaned dataset and the visualizations/dashboard.
What if my dataset is very large or very messy?
Let me know the size and condition before ordering. Very large or extremely messy datasets may need a custom quote rather than the standard package price.
